[Zope] manage_defined_roles pb.

[Didier Georgieff]

Hello,

I've created a Zclass, with a need for some roles.
So i've created a setup method (localized on the root folder) for 
adding this role.

Looking at the ZMI code shows that this should work.

 <dtml-call "REQUEST.set('role','PopotoGest')">
 <dtml-call "REQUEST.set('submit','Add Role')">
 <dtml-call "manage_defined_roles(REQUEST['role'],REQUEST['submit'],)">

This raise no error BUT doesn't create the role.
Did I missed something ? And what ?

Thanks in advance.
